I would agree, except for one point; If the share price ever takes off, it will make Marcus a very very rich man. He would be worth a lot more than running a privately held company; even with taking in a large salary.
This is just my opinion, I think a company is more valuable when it's public, as more people are aware of it and have access to the company's financials which adds to the demand for the company's shares depending how good they are doing. If they are private and doing well, then only a few people close to the company are aware of the value.
I've read posts about going public quite a few times, but I don't think there's a solid understanding of why businesses go public and what it takes to go private (less than 300 shareholders is a tough nut to crack - there are likely thousands).
The likelihood of any consideration of going public is extremely small. It's too long and involved to cover every time this comes up and I'm busy, so...JMO (and without support, I know)
